Hybrid Turkeys, a Kitchener, Ont.-based company, is one of the largest turkey breeding companies in the world.

The video, available for viewing at www.turkeytorture.ca, also shows workers crushing the spines of turkeys and bashing their heads with metal rods and shovels.

Several turkeys in the video had open wounds, rotting eyes and festering infections.

According to the turkeytorture.ca website, a Mercy for Animals Canada investigator worked at the Bright farm between December 2013 and February 2014. During that time, the secret video of the alleged abuse was filmed.

The video has prompted investigations by the Ontario Provincial Police and the Ontario Society for the Prevention of Cruelty to Animals. After viewing the video, four employees were suspended by Hybrid Turkeys, a release issued by the company stated.

"Hybrid has pledged to fully participate in any and all investigations regarding the matter," the release stated.

Some time last week, the company announced video monitoring of all bird euthanasia at their farms. A third-party investigation to review the company's policies and procedures is also underway.

"As an innovative, responsible company, Hybrid Turkeys is continuously looking for ways to improve our flocks and the care that we provide them at all stages in their life cycle," David Libertini, managing director at Hybrid Turkeys, said in a release.

"The co-operative research initiated with the Campbell Centre for the Study of Animal Welfare will investigate ways to enhance the care and welfare of our turkeys."
